MOSCOW: Russia on Thursday sweltered in abnormally hot summer weather as the emergency services sought to control expanding countryside blazes to prevent a repeat of last year's devastating wildfires.
The central city of Volgograd was Russia's hottest city with temperatures hovering above 40 degrees Celsius (104 Fahrenheit) for the past few days, hotter than Cairo, Tashkent, Tehran and New Delhi, weather forecasters said.
Local officials issued repeated heat alerts, warning residents of the former Stalingrad, scene of the savage World War II battle against the Nazis, to expect tropical heat of up to 43 degrees C (109.4 F) on Thursday.
"The world once again admires the courage and tenacity of Volgograd residents," said Fobos weather forecasting service. "The temperature in the city has exceeded 40 degrees for the third day in a row."
Russia endured the worst heat wave in its recorded history last year when wildfires spread out of control, killing dozens of people, burning down thousands of houses and threatening military and nuclear installations.
For the past week Russians have been struggling with a new heat wave although it is not as severe and appears to be waning.
Thursday is expected to be the last day of suffocating heat in central Russia, according to the Fobos forecasters. In Moscow, temperatures are expected to spike at between 33 and 35 degrees C (91.4 and 95 F).
"The heat wave will begin to abate from Friday," Leonid Starkov, a Fobos meteorologist said.
At 33.6 degrees C (92.5 F), Wednesday was the hottest day since the start of the year in Moscow.
"In many ways, the weather is reminiscent of the one last year," Fobos said, adding however the heat was not as intense. By comparison, the temperatures stood at 35.7 degrees C (96.3 F) on Wednesday.
The hot dry air was fanning wildfires across Russia and the area covered by blazes grew by some 3,000 hectares (7,500 acres) to more than 21,500 hectares in the past day, the emergencies ministry said.
A total of 192 fires continued to burn across Russia, down from 220 registered on Wednesday, it said.
Russian subways and residential buildings, most of which still date from the Soviet era, are ill-equipped to cope with extreme temperatures.
Mass-circulation newspaper Komsomolskaya Pravda said the temperature at the Moscow subway had exceeded permissible levels, ambulances made nearly 40 trips to the metro on Monday and Tuesday and one 47-year old passenger died of a heart attack.
Environmental campaigners warned earlier this year of a return of the noxious smog which enveloped Moscow last summer but no signs of it have been detected around the city so far.
As parched Russians take shelter in air-conditioned offices and pray for rain, at least one industry is looking to cash in on the hot-weather spell.
"During such hot days consumption of ice cream jumps by 10 percent a month on average," Gennady Yashin, deputy director of the Union of Russian Ice-Cream Makers, said.
The trade industry group expects Muscovites will have gobbled up between 330 and 340 tonnes of ice cream by the end of the month, up from 319 tonnes consumed in June.
That, however, would still be a far cry from last July, which saw a record-breaking amount of nearly 380 tonnes of ice cream eaten in Moscow in one month, said Yashin.
